Study in IRC

There are many people in IRC  Freenode-#ubuntu&-#kubuntu
I post my question there and many friendly person answer me immediately!
Today's tip:
>a great Terminal:Yakuake:


Install:
$sudo apt-get install yakuake
Alt-F2,  typing in "yakuake", then you can use F12 to open it.
but Yakuake will not autostart when you log in. So add it in session:
System-Preference-Sessions(add yakuake in 'Startup Programs')
have a good time!
